“It would be great if people had to buy more of the thing,” says guy who makes money selling the thing.
The problem is it’s kind of murky now since most discs don’t even contain the game anymore. So yeah you can lend/sell them but you’re still dependent on a digital store. It’s just a license for a digital game in physical form. I say this as a physical media proponent.
I am not pro-digital only but if the discs don’t have the game I’m less inclined to pay extra for what is likely to be the first part of my console to fail.
